Sissеton-Wahpeton Community College (the College) appeals from a judgment en *1042 tered by the district court in favor of Vicki Hagen and Colin L. Harris on their consolidated race discriminаtion cases. Because we hold that the College was a tribal agency immune from suit, we reverse.
BACKGROUND
In 1979, pursuant to its constitution, the Sisseton-Wahpeton Sioux Tribe (the Tribe) chartered thе College as a nonprofit corporation to provide post-secondary education to tribal members on the Lake Traverse Reservation. The College’s boаrd of trustees is comprised of one enrolled member from each of the Tribe’s seven districts. In 1994, Hagen and Harris, nonNative Americans, entered into one-year contracts with the Cоllege. After their contracts were not renewed, they filed race discrimination charges with the Equal Employment Opportunity Commission and the state human rights commission. Both commissions dismissed thе charges for lack of jurisdiction over Indian tribes.
Hagen and Harris then filed discrimination complaints in district court. Although the College’s president, Dr. John Derby, was served, the College did not answer the complaints. In April 1997, appellees filed a “motion for a judgment by default.” In June 1997, the court granted the motion and referred the matter to a magistrate judge to hold a jury trial on dаmages.
On July 3, 1997, after the jury awarded damages but before judgment was entered, the College entered an appearance and filed a motion to dismiss under Fed. R.Civ.P. 12(b)(1), raising subject matter jurisdiction and immunity arguments. In March 1998, the district court denied relief, stating that a “Rule 60(b)(4) motion need not be granted because of a belated finding no jurisdiction existed.” The court also stated “[wjhether or not the College might have been immune from suit in this Court is not the issue.” In any event, the court stated it had reviewed the materials the College had submitted in support of its motion, but found that they did not show the College was entitled to tribal sovereign immunity. The court then referred the matter of fees and costs to the magistrate judge.
After the award of fees and costs, in June 1998, the College filed a motion to set aside the default under Fed.R.Civ.P. 55(c), again raising lack of subject matter jurisdiction and sovereign immunity arguments. In February 1999, the district court again denied relief, stating it was “too late” to consider the College’s immunity argument.
DISCUSSION
The College first argues that the district court erred in treating its Rule 12(b)(1) motion to dismiss as a Rule 60(b)(4) motion for relief from a judgment. We agree. At the time the College filed the motion, judgment had not yet been entered. As the College notes, Rule 12(h)(3) provides “[wjhenever it appears by suggestion of the parties or otherwise that the court lаcks jurisdiction of the subject matter, the court shall dismiss the action.” In addition, the district court’s order granting appellees’ “motion for a judgment of default” was erroneous “becausе a default judgment cannot be entered until the amount of damages has been ascertained.”

Because the facts are undisputed, we address the College’s argument that it is immune from suit. Initially, we note in this cirсuit, “[sovereign immunity is a jurisdictional question.”
Rupp v. Omaha Indian Tribe,
The College argues because it is chartered, funded, and controlled by the Tribe to provide education to tribal members on Indian land, it is a tribal agency. The College relies on

and

Hagen and Harris argue that even if the College enjoys immunity, it waived immunity by failing to answеr their complaints. We disagree. “In
Santa Clara Pueblo v. Martinez,
Contrary to appellees’ suggestion, neither

We also reject appellees’ argument that the College waived its immunity because of a “sue-and-be-sued” clause in the College’s charter in effect at the time their contracts were not renewed. The charter provided that the College could “sue and be sued in its corporate name in a competent court to the extent allowed by law.” It also provided that the Tribe gave its “consent to allowing the [College] to sue and be sued upon any contract” and “au-thorizеfd] the [College] to waive any immunity from suit which it might otherwise have.” Appellees acknowledge that in
Dillon
this court held that a similar clause did not waive immunity, but argue the case was wrongly decided. In

Weeks Constr., Inc.,
The College argues that, except for
Dillon,
the cases are distinguishable. It is true that
Weeks
was a breach of contract case and in
A & P Steel
the immunity issue arose in the context of a contract counterclaim. Although we are inclined to believe the differences are immaterial and our cases are in conflict,
see also Rosebud Sioux Tribe v. Val-U Constr. Co. of South Dakota, Inc.,
Despite our holding, we note the College’s failure to raise the motion earlier has resulted in delay, expense to appellees, and waste of judicial resources. Nonetheless, because “[sovereign immunity ... is a jurisdictional prerequisite which may be asserted at any stage of the proceеdings, ... [a] Court simply cannot ignore arguments, however belated, that call into doubt the Court’s authority to exercise jurisdiction over [a] matter.”

Notes
. Although we question the court's authority to refer the case to the magistrate judge for a damages trial,
see J.C. Henry v. Tri-Serv., Inc.,
. Nor did the College waive its immunity by executing a certificate of assurancе with the Department of Health and Human Services in which it agreed to abide by Title VI of the Civil Rights Act of 1964.
